Application

Teriflunomide has been used as a dihydroorotate dehydrogenase (DHODH) inhibitor.

Biochem/physiol Actions

Teriflunomide is an orally available anti-inflammatory immunomodulator. It blocks the activity of dihydroorotate dehydrogenase, preventing pyrimidine synthesis and T and B cell proliferation and function. Teriflunomide has been used to treat rheumatoid arthritis and was recently approved for multiple sclerosis.
